ThisA invention relates to val-vesrandpartoularly to valves of the reed type.

In this type of valve theA gas passage through the valve.. basecommunicateswith a U-shaped slotin which a similarly shaped valve is placed to close the gas passage. The valve is clamped at its base against the valve seat by a splitter vane which permits the valve to bend away from the seat for gas to flow through the gas passage. It has been found' advantageousY to have the valve clamped resiliently as in the co-pending application of Ward, Serial No. 520,070, led January 28, 1944, now Patent No. 2,496,834, in which the splitter vane has resilient ears contacting with the clamping rings that hold the splitter vane-in place. A feature of this invention is-an arrangement of the splitter vane such that the ,resilient clamping action takesl place between thefvalve and: the splitter vane rather than between the splitter vane and the clamping rings. Another feature is the provision of resilient clamping ngers on the splitter vanerfor eng-agement directly with the valve.

A feature of this invention is the provision of rugged clamping ears with the resiliency necessaryV in a multiple valve assembly provided by a resilientconnection between eachv splitter vane and'the associated Valve.

Other objects and advantages `will be apparent fromthespecification and claims, and from the accompanying drawings which illustrate an ernbodiment of the invention.

Fig. 3 is a sectional view on the lineV 3 3 of' Fig. 1.

Fig. 4 is a perspective `View of the splitter vane.

Fig. 5 is a sectional View correspondingV to Fig. 3. showing a` modification.

As best shown in Figs. 1 and 2; the valvebase l0 is mounted in a supporting structure consisting of spaced annular rings l2 and M which may beintegrally connected together as by a series of Webs I5. The valve base is positionedbetween these-two rings and'has projecting flanges It. and lengaging shoulders 2? and 22 provided by the supporting structure.

The valve base has a number of annular grooves 24 extendingV inwardly from one side surface thereof which intersect with U-sh-aped slots 23 positioned radially and extendinginwardly from the other side surface of the valve base. The intersecting slots form gas passages 28 extending through the base for the iiow of air therethrough.

The gaspassagesare .closed'by U -shapedvalves llpositionedin theslots 2S -asshownin Fig. 3. The valves are heldin position byA splitter vanes 3,2, the lower; edgesof which have slotslZ form: ingv spaced projecting` ribs or fingers. 3B which clamp -thevalve securely inY thev baseof theslots. The ribsare.` normally parallel asshown in Fig. 4 and move resiliently toward one another as the splitter vane, is pressed into` clamping position, It, will Vb eunderstood that thesplitter vane` isl-of such; a shape.l as'shown in Fig. 3, that the-outer free edgesof Vthe valve may move away; fromthe Walls of the slot andagainst the splitter vane-to open the gasv passagesifor a flow of-airrthrough the-valve base.

Theset of splitterfyvanes whichhold the valves in position are clamped 4in. place-by clamping rings 3 8 and fwhichgengage withA ears 40, projecting rigidly fromVv opposite ends of the-splitter; vane. Asshown inV Fig. 3, these -ears orflugs-Ml arelintegra-l with the; splitter vane and ,f areI long: enough toA extendnover; and engage with theouterand innersurfacesfor thel valve base tolimit-the endwise `movement ofthesplttervanes. The-clamping rings 3,8and 39,-'closetheendsofthe slots26 and. engage with the entire set of lugs; on; the splitter vanes. The rings may be threadedn as indicated in Fig.. 2- soA that the rings,` may be screwed; downv tightly against the,v splitter vanes, thereby` holding the; vanes securely` against the bases of ther valves'y and` clamping the valvesl securely against the, valve base. Thel clamping rings; also functionY to hold-,the flanges I6 and; I8 onthegvalve base, in secureengagement with the shoulders. 211M 211111122:Onathefsnpporting structure; It; will be; understood: that: the 1eil-encr` plvvided-by the-ribs SliY adjust/Safor any'non-uniformity-resu1tngffrom manufacturing tolerances and assures that each.v valve;will;l be; securelyclamped in position.

Insteadof thefintegralresilientanges on the splittervane; as inFigs;- 3 andl, the splitter vane mayhavev special; resilient strips 42 mounted thereonL'asby rivets ,54, as sl^lownin;lig.V 5. The splitter; vane,-y 4 8v is otherwise of the: same. con,- structionasthe splitter vane 3 2 andv functions to holdavalve-Sil inplace within; the valve base l0. Itl has beenrfound, in lightweight valve structures, thatV a magnesium or aluminum splitter vanemightnot have snfiicient inherentresiliency, so that it;wouldbedesirable vto use separate strips of a; material having a higher elasticity to provide the resilient clamping action for the valve.
